Review on 🌊 FUNUS Big Water Bottle BPA Free Half Gallon Water Jug: Wide Mouth, Reusable, and Perfect for Fitness, Sports, Gym, and Outdoor Climbing - Nebulas Blue, 2.2L by Joshua Turner

To be honest I don't know where to start. One of the main advantages is that it is not bulky. 2 liters holds without problems. Keeps me hydrated all day without having to refill. The only problem I have is the whistle when I drink. I was in class an hour ago and decided to have a drink. Next thing I know, everyone's looking at me for the whistle. XDI recommends making the compensation hole a millimeter or two larger to avoid annoying whistling.
